Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1734775-1 are classified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

Connector Type: USB-A (USB TYPE-A)
Specifications: USB 2.0
Number of Contacts: 4
Gender: Receptacle
Mounting Type: Through Hole, Right Angle
Mounting Feature: Vertical, Flag
Termination: Solder
Features: Board Lock
Shielding: Shielded

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS3 requirements, ensuring compliance with current regulatory standards. The TE Connectivity 1-1734775-1 represents a direct parametric equivalent from the same manufacturer with identical electrical and mechanical specifications and enhanced inventory availability (4968 units).

Molex series parts (0482040001, 0673298000, 0673298001, 0673298020, 0673298021, 0894858000, 0894858001, 0894858002) provide alternative sourcing from an established connector manufacturer. These parts maintain all critical substitution parameters and carry ROHS3 compliance with REACH Unaffected status.

The Adam Tech USB-A-S-RU connector offers an alternative from a third-party manufacturer while maintaining all core electrical and mechanical specifications required for direct substitution.

Selection among substitute parts should be based on inventory availability, lead time requirements, and supply chain considerations, as all parts satisfy the functional and compliance requirements of the TE Connectivity 1734775-1.
